In this article, I will explain as clearly and concisely as possible the difference between a CSS class and a variable, so that you understand how to use them effectively.
Variable VS CSS Class
A variable is a style property (size, color, font, etc.).
→ A variable = A style
In contrast, a CSS class acts like a "folder" that groups together multiple styles (size, color, font, spacing, and even variables). It is applied to HTML elements to give them a distinct design.
→ A CSS class = One or more grouped styles
💡 Tip: Variables can be linked to one or more CSS classes, making style updates smoother and more manageable across websites.
Usage Example
In practice, a style change in a CSS class will only affect the HTML elements that share that class. On a "large" site, as classes multiply, global adjustments like colors or spacing can become lengthy and complicated.
In contrast, a variable is a more dynamic value. Once its property is changed, it will automatically update everywhere it is used within your CSS classes.
In short, when used correctly, one does not go without the other in front-end development. Connecting variables to your CSS classes will allow you to:
- Maintain a consistent design
- Save time during development
- Be able to make swift updates
